Interesting dream! Here are a few thoughts that came to my mind regarding what various aspects of it might symbolize:
You and your ex as children: innocent, vulnerable aspects of your psyche, parts of you that need to be nurtured and guided.
Fire: Fire often means anger (how many times have you heard someone say they were "burning up" when they were mad, or that someone has a "fiery temper"?)
Home with your ex: The home you were in may symbolize your relationship together.
Fire in the home: Anger in your relationship.
You were the only one trying to put the fire out; your ex didn't care. Is that reminiscent of your break-up? Did you feel that you were the one "putting out the fires" while he just sat there?
As for the waking dream: the figure on the bed was resisting the dr's and nurses. Seems symbolic of a struggle you are having with accepting what it takes to heal, perhaps because it seems too painful to face, like an unpleasant medical treatment?
Sweet dreams!
